It should not matter on the year, if anything the 18' is the most difficult because GM can't leave anything alone. I got curious on the HPT update's your brought up, so this morning I have been rolling through the previous versions of HPT, so far, the past 4 updates have everything needed to get flex up and moving.

And yes Cooper1965 is correct, many many tables to adjust to get a strong and safe combo. You can expect and easy 30-50HP more when on corn fuel and properly tuned.

When I switched mine over I went from lo 13's to mid 12's!

I used service terminal 7116-4152-02, it is in Yazaki tray 9, to connect to the PCM. (That "could" be different depending on year, I did not check)
